At the moment errors due to invalid arguments are not very clear and misses informations about which function caused the issue.

MongoshInvalidInputError: [COMMON-10001] Argument at position 0 must be of type string, got number instead

Just reporting some comments from slack about this topic:

"if we’re not showing any stack trace information by default, could we make a ticket to at least make sure that our basic input validation (assertArgsDefined and friends) always print the function name as well?"

and:

"I think that would be cool, and a bit more user friendly even.
Like instead of at position0 could we say something like NumberDecimal should be called with a string, e.g. NumberDecimal("1.5")"
